Generator Application

The generator application is contained in bundle org.eclipse.equinox.p2.metadata.generator. This bundle is part of the Eclipse SDK, and is also available in the p2 Admin UI. The generator can be invoked using the generic Eclipse launcher as follows:

Want to simplify that down to a shell script with a couple of inputs -- site name ("Ganymede") and site path ("d:/ganymedeM5/")? Try this script, which will be simpler still when the p2.metadata.generator bundle gets added to releng.basebuilder (bug 229916):

Arguments describing the input

-source <path>

the path to a folder containing plugins and folders to contain p2 metadata for

-updateSite <path>

the path of a traditional update site to generator p2 metadata for

-config <path>

the path of an Eclipse application that is not p2-enabled

-exe <path>

the location of the application launcher executable

-launcherConfig <path>

the path of the launcher configuration file (eclipse.ini)

-features <path>

the location of features to generate metadata for

-bundles <path>

the location of bundles to generate metadata for

-base <path>

a base location containing a plugins/ and features/ directory

-p2.os

the operating system of the application metadata is being generated for

-site <path>

Arguments describing the output

-metadataRepository

the URL to a writable metadata repository that will contain the produced installable units

-metadataRepositoryName

a user friendly name for the metadata repository

-artifactRepository

the URL to a writable artifact repository that will contain the produced artifacts

-artifactRepositoryName

a user friendly name for the artifact repository

-publishArtifacts

flag indicating whether the artifacts should be published to the repository. When this flag is not set, the actual bytes underlying the artifact will not be copied, but the repository index will be created. When this option is not specified, it is recommended to set the artifactRepository to be in the same location as the source (-source)

-publishArtifactRepository

-append

flag indicating that repositories will be appended to

-root

The name of the installable unit referring to all the IUs that have been added to the repository during the run

-rootVersion

The version of the root installable unit

-flavor

the flavor associated with the configuration units generated. (This will be removed for 1.0)

-inplace

causes the metadata and artifact repositories to be written into the source location

-noDefaultIUs

flag to indicate the default configuration units should not be created

-compress

cause the repositories to store their index in compressed form

-reusePack200Files

publish the existing pack200 files in the repository. This works when the artifact repository is generated in the source.

Generator Ant Task

The generator Ant task is called "p2.generator". This task is also available in the org.eclipse.equinox.p2.metadata.generator bundle.
